datapreprocess.impute action doesn't fill missing values in the output table

[Melhamamsy]

Hello all,

I'm trying to use datapreprocess.impute action to impute interval variables with their medians. However, when inspecting the output table, the missing values are not imputed.

The code is shown below, and, this is part of the "High-Performance Data Processing with CASL in SAS Viya" Course.

proc cas;
    inTbl={name="cars_raw", caslib="casuser"};
	outTbl={name="cars_imputed", caslib="casuser"};

    table.upload / 
        path="&path/data/my_data/cars_raw.sas7bdat"
        casOut=inTbl || {replace=TRUE};

    table.columnInfo /
        table=inTbl;

    simple.distinct / table=inTbl;

	datapreprocess.impute /
		table=inTbl,
		casOut=outTbl || {replace=TRUE},
		inputs={"EngineSize","Cylinders"},
		methodInterval="MEDIAN",
		copyAllVars=TRUE;


    table.columnInfo /
        table=outTbl;

    simple.distinct / table=outTbl;
quit;

Appreciate your explanation on this.

It's creating new variables with the imputed results:
